The pressure on President Obama to pardon Edward Snowden ramped up this week when a presidential panel affirmed that the former contractor’s leaks showed the National Security Agency had gone too far in its massive surveillance program. Snowden’s allies say he’s a hero for revealing the vast extent of the NSA’s spying program on Americans. His detractors, including the head of the NSA -- who was shown by leaks to have lied to Congress about collecting data on millions of Americans -- say he should be hanged for treason. What’s your view?
